Can you solve this real interview question? Intersection of Two Linked Lists - Given the heads of two singly linked-lists headA and headB, return the node at which the two lists intersect. If the two linked lists have no intersection at all, ...
Input:intersectVal = 0, listA = [2,6,4], listB = [1,5], skipA = 3, skipB = 2Output:No intersectionExplanation:From the head of A, it reads as [2,6,4]. From the head of B, it reads as [1,5]. Since the two lists do not intersect, intersectVal must be 0, while skip...
【leetcode76】Intersection of Two Arrays II 题目描述: 给定两个数组求他们的公共部分,输出形式是数组,相同的元素累计计数 例如: nums1 = [1, 2, 2, 1], nums2 = [2, 2], return [2]. 原文描述: Given two arrays, write a function to compute their intersection. Example: Given nums1 = [...
Your code should preferably run in O(n) time and use only O(1) memory. 首先定义两个指针,分别遍历两个链表,得到链表长度。然后求长度差,得出两个链表的差值。开头定义的两个指针回到链表头部,让较长链表的指针先移动差值距离,然后两个指针一起向后移动,直到两个指针所指向的地址相同,即为所求交叉点。
题目链接https://leetcode.com/problems/intersection-of-two-linked-lists/ 题意很好懂,问题在于如何找到相交的node,想到的最简单的方法从node的最后一个节点去往前数,遇到分叉,则返回当前节点,否则返回None。这里用 两个list去保存node,从list的最后一个位置开始往前进。 代码如下,提交后,超过 99.84% 提交代码的...
LeetCode 160. Intersection of Two Linked Lists题目分析 其他 请写一个程序,找到两个单链表最开始的交叉节点。 ** 注意事项 ** 如果两个链表没有交叉,返回null。 在返回结果后,两个链表仍须保持原有的结构。 可假定整个链表结构中没有循环。 样例 下列两个链表: ...

输入:intersectVal = 2, listA = [0,9,1,2,4], listB = [3,2,4], skipA = 3, skipB = 1输出:Intersected at '2'解释:相交节点的值为 2 (注意,如果两个链表相交则不能为 0)。 从各自的表头开始算起,链表 A 为 [0,9,1,2,4],链表 B 为 [3,2,4]。在 A 中,相交节点前有 3 个...
